Half of Arizonans surveyed over the weekend believe that President Donald Trump should not announce a pardon for former Maricopa County Sheriff Joe Arpaio at a Tuesday rally, compared with 21 percent who said it would be a good move, according to a new poll.

As of Monday evening, though, Trump's intentions on the matter remained unclear — at least to Arpaio. At 4 p.m., he told The Arizona Republic he'd yet to hear from Trump's people or receive an invitation to the rally.

The Phoenix-based polling group OH Predictive Insights surveyed 1,065 Arizonans from Friday to Sunday, asking: “This coming Tuesday, President Donald Trump will be in Arizona to hold a rally. Do you think President Donald Trump should pardon Sheriff Joe Arpaio at the event?”

The poll by found stronger support for Arpaio among older respondents. While 31 percent of those 55 or older believe Arpaio should be pardoned, the figure drops to 15 percent for those 54 or younger.

“Half of Arizonans say pardoning Sheriff Joe Arpaio at the Phoenix rally is a bad choice,” OH Predictive Insights Managing Partner Mike Noble said in a statement. “Another interesting takeaway from this survey besides Arizonans overall thinking an Arpaio pardon is a bad idea, it will go over like a lead balloon with the 54 years of age or younger crowd.”

The two are both immigration hardliners, and the pardon would be seen as repayment for Arpaio's loyalty. Arpaio, a polarizing yet wildly popular figure among conservative circles, was one of Trump's earliest supporters and introduced the then-candidate during his campaign visits to Arizona.

Last month, a federal judge found Arpaio had intentionally violated a judge's orders amid a long-running racial-profiling case. He is scheduled to be sentenced Oct. 5, and could face as many as 6 months in jail.
